Miami Realtors + RWorld has completed its second merger in just over two months, joining with Martin County Realtors of the Treasure Coast to create a single association and multiple listing (MLS) service spanning five counties in southeast Florida.
The merger expands the organization to approximately 94,000 members across Miami-Dade, Broward, Palm Beach, Martin and St. Lucie counties while strengthening its position as the nation’s third-largest MLS, leaders said.
“The merger that created Miami Realtors + RWorld is about building the strongest possible organization for our future,” said Dionna Hall, co-CEO of Miami Realtors + RWorld, who will become the organization’s sole CEO in 2027. “The addition of Martin County Realtors of the Treasure Coast reinforces that vision and demonstrates the value of creating an organization that delivers more data, more innovation, stronger advocacy and greater opportunities than any one association could provide alone.”
The merger creates what the association describes as the most complete South Florida MLS dataset and completes the unification of the Treasure Coast marketplace within the regional MLS network.
Miami Realtors merged with Broward, Palm Beaches & St. Lucie Realtors (RWorld) in April.
“From Miami-Dade to St. Lucie, a nearly 120-mile real estate corridor, we are one,” said Teresa King Kinney, co-CEO of Miami Realtors + RWorld. “We are honored to welcome Martin County Realtors of the Treasure Coast and their outstanding leadership, professionals and programs.”
Founded in 1926, Martin County Realtors of the Treasure Coast brings nearly a century of member service to the combined organization, including its weekly Market Watch program.
“Our members have spoken with overwhelming support for a future built on greater opportunity,” said Janet O’Brien, CEO of Martin County Realtors of the Treasure Coast. “This merger honors the proud legacy of Martin County Realtors of the Treasure Coast while providing our members with expanded resources, enhanced services and a stronger regional presence.”
The combined organization now serves nearly 7 million residents through 15 offices across Southeast Florida.
Members of the merged association gain access to the region’s combined MLS dataset, both Flexmls and Matrix platforms, free IDX feeds from MIAMI MLS and BeachesMLS and more than 2,800 educational programs annually.
Benefits also include more than 300 products and services, 300-plus global partnerships, free Supra access, more than 11 data-sharing partnerships and expanded advocacy representing roughly 93,600 Realtors.
